TECHNICAL FIELD

The present invention relates to the field of providing network access.More particularly, the present invention relates to providing content toa user accessing a network.

BACKGROUND

The internet is a vast array of interconnected computers which shareinformation with each other. The internet has become an important arenafor sharing, storing, transferring, searching for information, andtransacting business. Increasingly, the general public is able to accessthe internet in a wider range of locations. For example, public accessto the internet is becoming increasingly popular in locations such ashotel rooms, airports, and coffee shops. However, local network accessproviders have little control over the content requested and viewed by auser.

SUMMARY

Aspects of the present disclosure include systems and methods forinjecting content into a webpage at or local to a network access gatewayas well as remote to the gateway. For example, in an embodiment, anetwork access gateway is provided for accessing the internet. A userlogs onto the internet through the network access gateway and requests awebpage. The gateway requests the webpage from the webpage provider.Before the gateway delivers the webpage to the user, the gateway, or acontent injection engine local or remote to the gateway, injectscontent, such as, for example, advertisements or other usefulinformation, into the webpage and then sends the altered webpage to theuser. In some embodiments, the content injected replaces some or all ofthe content provided by the webpage provider. In some embodiments, thecontent injected adds to the content provided by the webpage provider.When the user views the webpage, the user views the access provider'scontent rather than or in addition to the webpage provider's content.

In an embodiment, the injected content includes advertising related toor associated with the local network access provider. In an embodiment,the injected content includes user inputs for allowing a user tocommunicate and transact with the local network access provider orothers associated with the local network access provider.

In an embodiment, advertising content is injected. In an embodiment, theadvertising content is provided from a local advertising content system.In an embodiment, the advertising content is provided from a remoteadvertising content system. In an embodiment, the advertising content isprovided by both a local and remote advertising content system. Localherein refers to a system which is not accessed through a network, butwhich is locally connected. Remote herein refers to a system which isaccessed through a network independent of the system's location.

In an embodiment, content is provided based on a user's history of use.In an embodiment, content is provided based on a user's specifiedpreferences. In an embodiment, content is provided based on userprovided information, such as, for example, length of visit, requestedservices, demographic information, or the like. In an embodiment,content is provided based on the type of device used to connect to thenetwork. For example, content provided to a user accessing a networkthrough a personal digital assistant (PDA) can be different than contentprovided to a user accessing a network through a laptop or cell phone.

In an embodiment, a management system provides content to a contentinjection engine. The management system provides content that allows auser to select services and service preferences of a particular venue,such as, for example, a hotel, restaurant, convention center, airport,business, or the like. In an embodiment, multiple separate systemsprovide content to a user, such as, for example, a restaurant managementservice, a housekeeping management service, a front desk managementservice, or the like.

In an embodiment, a subscriber management system allows a user to savepreferences so that each time the user visits a particular location theydo not have to reenter their preferences. In an embodiment, thesubscriber management system is local to a particular location. In anembodiment, the subscriber management system is remote to a particularlocation. In an embodiment, the subscriber management system is used toprovide user preferences to multiple locations. For example, In anembodiment, the subscriber management system provides user preferencesto individual hotels in a particular chain of hotels. In an embodiment,user preferences are shared between multiple hotel chains. In anembodiment, user information is shared throughout a range of networkaccess provider locations servicing various industries.

In an embodiment, a local or remote system, such as an advertisingprovider system, management system, subscriber management system, thesame or the like provides a different look and feel for the injectedcontent based on the user and/or the location. For example, contentinjected into webpages provided to a user at one hotel chain may lookdifferent than content provided to a user at a different hotel chain.Similarly, content provided to a particular user specifying a particularset of preferences may be different than content provided to a differentuser specifying different preferences.

In an embodiment, the network gateway device injects the content. In anembodiment, the network gateway works in cooperation with a separatecontent injection engine to inject content. In an embodiment, thenetwork injection engine injects content before it is received by thegateway device. In an embodiment, the network injection engine injectscontent after it is received by the gateway device. In an embodiment,the network injection engine is local to the gateway device. In anembodiment, the injection engine is remote to the gateway device. In anembodiment, an injection engine injects content for a plurality ofgateway devices.

In an embodiment, the injected content is persistent. For example, in anembodiment, the content injection engine checks the user's device toconfirm that the content is still visible on the user's screen. Asanother example, in an embodiment, the content is maintained on top ofother applications on the user's screen so as to be continually visible.In an embodiment, the content is injected independent of the website ornetwork content requested.

In an embodiment, a system for injecting content is disclosed. Thesystem includes a network access gateway and a content injection engine.The content injection engine injects content into the requested networkcontent. In an embodiment, the network access gateway and the contentinjection engine are included within the same housing.

DETAILED DESCRIPTION

FIG. 1A illustrates an embodiment of a content injection system 100. Auser uses a client device 101, such as, for example, a computer, laptop,personal digital assistant (PDA), cell phone or the like, to connect toa gateway device 103. The connection can be wired or wireless and can beused with any available wired or wireless communications protocols suchas, for example, Ethernet, Bluetooth, IEEE 802.11a-n, or the like. Onceconnected to the gateway device 103, the user can request informationthrough a network 107, such as for example, the internet. The gatewaydevice 103 communicates the user's requests to the content injectionengine 105. The content injection engine 105 communicates with therequested content server 109 through the network 107. The requestedcontent server 109 responds by transmitting the requested content to thecontent injection engine 105 through the network 107. The contentinjection engine 105 injects content into the requested content andtransmits the altered requested content to the gateway device 103. Thegateway device 103 transmits the altered requested content to the userdevice 101 which displays the altered requested content to the user.Some examples of a gateway device are explained in U.S. Pat. Nos.6,636,894 and 6,130,892, the disclosures of which are herebyincorporated by reference.

In an embodiment, the content injection engine 105 injects contentstored in the content injection engine 105. In an embodiment, thecontent injection engine 105 injects content supplied by a venueoperator server 111. In an embodiment, the content injection engine 105injects content supplied by a local ad or content server 113. In anembodiment, the content injection engine 105 injects content supplied bya remote content or ad server 115. In an embodiment, the contentinjection engine 105 injects content supplied from multiple sourcesincluding a venue operator server 111, a local content or ad server 113,and a remote content or ad server 115.

The local and/or remote ad or content provider servers 113, 115 providelocal or remote content and advertising. For example, the local ad orcontent server 113 may provide advertising on local restaurants, localevents, local activities, or the like. The local ad or content providercan also be used to provide non-locally related advertising. The remotead or content server 115 provides advertising and content to multiplenetwork access locations. The remote ad or content server 115 canprovide local or non-local advertising.

The local or remote venue operator server 111, 117 provides injectablecontent from the venue operator. For example, the venue operator servers111, 117 may inject advertisements specific to the venue. In anembodiment, the advertisements can be about the venue or can be targetedat venue users.

In an embodiment the content injection engine 105 and the gateway device103 are housed within the same housing 121 or integrated into a singledevice. The content injection engine 105 can operate independent of thegateway device 103 within the same housing, or the content injectionengine 105 may be an integral part of the gateway device 103.

FIG. 1B illustrates an embodiment in which the content injections engine105 is accessed through the network 107. For example, in an embodiment,when a user requests content, such as a webpage, the gateway device 103forwards the request over the network 107 to the content injectionengine 105 which then requests the content from the content provider.The content provider sends the requested content to the contentinjection engine 105 which injects content into the requested content.The content injection engine 105 then forwards the altered content tothe gateway device 103, which forwards the altered content to the user.

FIG. 1C illustrates an embodiment of a gateway device 103 which receivesrequested content directly from the network 107 and then forwards thereceived content to the content injection engine 105. The contentinjection engine 105 injects content and then forwards the requestedcontent with the injected content to the gateway device 103 for deliveryto the user. The content to be injected can be received by or stored inthe gateway device 103 or content injection engine 105. The content tobe injected can be received from various servers, such as, for example,the servers described above with respect to FIG. 1A. When it is receivedby the gateway device 103, the gateway device forwards the content to beinjected to the content injection engine 105.

FIG. 1D illustrates another embodiment of a content injection system.FIG. 1D illustrates various local management systems in communicationwith the content injection engine 105 which are used to inject contentregarding local services and information. The local management systemscan include, such as, for example, a restaurant management system 157, ahotel management system 159, a concierge service system 161, a localcontent/ad server 163, or any other local service systems. For example,in an embodiment, the content injection engine 105 injects localrestaurant information to allow a user to access information regardinglocal restaurants. In an embodiment, the injected content allows a userto make a reservation or order a delivered meal. In an embodiment, aconcierge service system 161 provides content based on local activities,local events, traffic, weather, local restaurants, directions, or thelike. In an embodiment, a hotel management system 159 allows a user tocheck in or checkout, provide preferences regarding hotel services,request a wake up call, or request information or services. AlthoughFIG. 1D is described with respect to hotel services, a person ofordinary skill in the art will understand from the disclosure hereinthat other venues, such as airports, convention centers, schools, or thelike, will provide similar content provider systems to provide a userwith local content and local transaction options.

FIG. 1D also illustrates the use of a local subscriber management system155 and/or a remote subscriber management system 153. In an embodimentof a subscriber management system, a user is allowed to save preferencesso that each time the user visits a particular location they do not haveto reenter their preferences. The local subscriber management system 155saves user preferences specific to the particular access location. Theremote subscriber management system 153 saves user preferences which aredistributed to multiple access locations. For example, in an embodiment,the subscriber management system provides user preferences to individualhotels in a particular chain of hotels. In an embodiment, userpreferences are shared between multiple hotels. In an embodiment, userinformation is shared throughout a network of network access providerlocations servicing various industries.

FIG. 2A illustrates an embodiment of a content injection systemutilizing a network operations center (NOC) 155. The network operationscenter can be used to manage multiple gateway devices and multiplevenues. The network operation center can be located remote or local to agateway device. The network operation center can also be physicallymapped to multiple locations for data redundancy and reliability. Thenetwork operations center can provide a variety of services including,such as, for example, redirection, authentication, billing, contentinjection, management services or the like.

FIG. 2B illustrates an embodiment of a network operations center 155.The network operations center 155 includes portals 201, access module203, partner services 207, and clearing house 205. Access module 203provides services which allow the network access system to redirect andchange the content viewed by a user's computer without the user havingto reconfigure the user's device settings. The access module 203 makesit appear to the user's device that it is receiving the requestedcontent when in fact the content may be different from that requested.Access module 203 can also provide content injection services to injectcontent into requested content.

Partner services 207 provides databases which track usage and expensesincurred by users and partners and provides usage reports, invoices andother services, such as, for example, technical support to partners. Apartner can be, for example, a gateway or venue owner or operator. Avenue can include one or more gateway devices providing network accessfrom one or more locations in the venue or throughout the entire venue.A venue can be a coffee shop, airport, convention center, cruise ship,plane, stadium, library, school or the like.

Clearing house 205 can include an authentication, authorization, andaccounting (AAA) server 206 and partner settlement server 209. In someembodiments of network access systems, only certain users are givennetwork access. For example, the users may be required to be part of aspecified group or may be required to pay for network access. Clearinghouse 205 provides services to allow a user to be authenticated andgiven access to the network. In an embodiment, the clearinghouse 205 isoperated by a third party. In an embodiment, the clearing house 205facilitates exchange of authentication and accounting messages betweenservice providers and home entities. Home entities are entities whichhave a prior relationship with the user. In an embodiment, the clearinghouse 205 provides auditable data for settlement of roaming payments. Inan embodiment, the clearing house utilizes RADIUS accounting. The AAAserver 206 provides information and services necessary to track allowedusers in order to grant the user access. For example, the AAA server mayinclude a list of allowed users with corresponding identificationinformation, such as, for example, a user name and password. The AAAserver may also include information concerning whether or not a user haspaid the required fees to access the network. The partner settlementserver 209 tracks the user usage and charges.

Portals 201 can include the web pages where users are initiallyredirected to before authentication occurs. The portals can includelocal information and advertising and can provide the vehicle to allow auser to enter information for authentication and payment.

FIG. 2C illustrates another embodiment of a network operations center155. The network operations center 155 includes portals 201, partnerservices 207, clearing house 205, application gateway 251, directory 253and AAA/virtual private network (VPN) 257.

FIG. 3A illustrates a flowchart of an authentication process 300.Authentication process 300 begins at block 301 where a user connects tothe gateway using a client device. At block 302, the gateway deviceredirects the user to a network operations center. At block 303, thenetwork operations center obtains a pre-authentication page and injectscontent into the pre-authentication page. At block 304, the new user ispresented with the pre-authentication page containing the injectedcontent. At block 305, the user inputs authenticating information and isauthenticated to the network.

FIG. 3B illustrates a flowchart of an embodiment of a content injectionprocess 310. The process begins at block 311 where a user requestsnetwork content using a client device in communication with a gatewaydevice. The request is forwarded to the requested content server whichreplies with the requested content. The process 310 then moves to block312 where the requested network content is received by the contentinjection engine. At block 313, the content injection engine injectscontent into the network content. The process 310 then moves to block314 where the network content with the injected content is sent to theuser's device.

FIG. 3C illustrates a flowchart of another embodiment of a contentinjection process 320. At block 321 a user requests network contentusing a client device. The user's request is then forwarded from theclient device to the gateway device. The gateway device forwards theuser's request to the content injection engine at block 323. The contentinjection engine forwards the request to the network at block 325. Thenetwork receives the request at block 327 and forwards the request tothe appropriate server which responds to the users request with content.The content is then sent from the network to the content injectionengine at block 329. The content injection engine determines the contenttype at block 331. The content type can be, for example, HTML, content,PDF content, audio-visual content, executable content, or any other typeof content sent or received from a network system. Based on the content,the content injection engine injects content into the content receivedfrom the network. For example, if the content is HTML, the contentinjection engine parses the content at block 333, and injects newcontent at block 335. The altered content is then forwarded to thegateway device at block 337. The gateway device forwards the alteredcontent to the client device at block 339. The altered content isdisplayed at block 341.

FIG. 4A illustrates one example of a webpage with injected content.Webpage 401 includes original content 403 and injected content 405.Injected content 405 is included in a frame of the webpage 401. Theframe may be of any shape, size, configuration or orientation. Forexample, the frame may be in the middle or on the right side of thewebpage.

FIG. 4B illustrates injected content 425 in a frame or section of thewebpage 421 of the original content 423. The frame or section of thewebpage in which the injected content is placed can be a pre-existingframe or section, or a newly created frame or section, created by thecontent injection engine. The content injection engine 105 injectscontent independent of the content or the site from which the content isreceived. In an embodiment, content is injected in the form of an XMLapplication. In an embodiment, content is injected in the form of anHTML, application. In an embodiment, the content is injected in the formof a macromedia application.

FIG. 4C illustrates an embodiment in which the content is injected intoan XML or other application 445 of webpage 441 so as to be floating overoriginal content 443. The XML application can be pre-existing to theframe or can be created by the injection engine.

The content to be injected can be delivered in any number of ways. Forexample, In an embodiment, the injected content is delivered in realtime. In an embodiment, the content is stored on a remote or localserver or on the portal server, gateway, or content injection engine. Inan embodiment, content to be injected is stored and updated in real timeor as needed.

The injected content can be chosen based on any of a variety ofindications about the user. For example, the injected content may bebased on the user's location, for example, as determined by the gatewaydevice providing access. The content injected can also be determinedbased on metadata or other information contained in the requestedcontent. The content injected can also be based on the past browsinghistory of the user or on preferences selected by the user. The contentinjected can also be based on the personal information obtained throughthe authentication processor from a venue provider. A person of skill inthe art will understand from the present disclosure that many otherindications about a user can be used to determine a type of content toinject into requested content.

In an embodiment, the content injected can be injected into any contenttype transferable over a network connection, such as, for example, HTML,PDF, Flash, streaming media, static media, or the like. In anembodiment, the content injected content can be of any type transferableover a network connection, such as, for example, HTML, PDF, Flash,streaming media, static media, or the like. In an embodiment, theinjected content type is different than the content type into which thecontent is being injected. For example, streaming media can be injectedinto static content. In an embodiment, the content injection engine maycommunicate with other inline devices, such as, for example, thegateway, in order to increase the bandwidth allotted for a given user oruser's channel so that the injected content does not affect the networkperformance of the user.

In an embodiment, the content injected is based on the content requestedby the user, and not on information requested or fetched by the UserKiosk application.

In an embodiment, the User Kiosk is customizable. The User Kiosk can becustomized by the user to include only specified content or expanded toinclude third party applications. In an embodiment, preferences relatedto the User Kiosk can be saved, for example, in the subscribermanagement server so that when a user moves to a new location, the UserKiosk includes the user's previously set preferences.

Although FIGS. 5A-6C are described in relation to a hotel stay, one ofordinary skill in the art will recognize from the disclosure herein thata similar virtual business center can be used in relation to othervenues, such as, for example, a convention center, a library, a school,a business, a restaurant, shops, or any other network access venue.

FIG. 7 illustrates a flowchart of the operation of a heart beat orpersistent content check process 701. When content is injected intorequested content, it can be desirable to confirm that the content isstill visible and/or included in the requested content. For example, ifan advertisement is injected into the content, it may be desirable toconfirm that the advertisement is still viewable and/or included in therequested content so as to gain the attention of the user. In anembodiment, a heart beat, or signal, is sent periodically from theinjected content on the user's device to the content injection engine orother monitoring system. A heart beat monitor performs the function ofchecking to see if the content is still present and/or visible on theuser's device. If the heart beat is not sent, or stops being sent, thenthe content injection engine assumes that the injected content is notpresent and/or displayed and initiates a process to re-inject thecontent.

In a browsing experience, this heart beat can be implemented asJavaScript code run in a frame. If the content's parent window isclosed, this framed window will also close and the heartbeat will stop.This will trigger the content injection engine to re-inject the contentat the next data request from the user. In an embodiment, the heartbeatmechanism is implemented using a macromedia flash applet downloaded forthe window or as part of a User Kiosk application/applet that can bedownloaded by the user.

The process 701 begins at block 705 where user requested content isreceived. Content is injected in the requested content at block 707. Theprocess 701 continues by looking to see if the injected content is stillpresent and or displayed on the user's device at block 709. If theanswer is yes, then the ad rotator counter is updated at block 711. Ifthe answer is no, then the system moves to block 713 where the processreinjects content or waits for a new user access request to reinjectcontent.

Although the foregoing invention has been described in terms of certainpreferred embodiments, other embodiments will be apparent to those ofordinary skill in the art from the disclosure herein. For example,although the disclosure has been described with respect to certainembodiments and certain programming languages, a person of ordinaryskill will understand from the disclosure herein that other programminglanguages can be used to accomplish any aspect of the presentdisclosure. As another example, although the content injection engine isdescribed with respect to injecting content, it is too be understoodthat injecting can mean both adding to the original content or replacingat least a portion of the original content. Additionally, othercombinations, omissions, substitutions and modifications will beapparent to the skilled artisan in view of the disclosure herein.
